" LUIGI VERNA, OF PHILADELPHIA, PENNSYLVANIA.

DRYrNG-Rooivr.

To dll whom, it may concern.'

Be it known that I, LUIGI VERNA, a citizen l of theUnited States, residing at Philadelphia,

useful Improvements in Drying-Rooms, of

which the following is a specification.

` My invention relates to improvements in a drying machine and particularly relates to a machine for drying alimentary paste or dough used in the manufacture of macaroni.

The object of .my invention is to construct a dryingmachine in which the dough can be quickly dried without causing the surface or crust of the dough to crack, this I accomplish by constructing the drying machine so that the dough may be sub'ectedv to an atmospheric pressure which wiil dry the dough uniformly without causing the surface to crack; a further object of my invention is to provide means for causing the air in the drylng-machine to circulate and also for admitting fresh air to the same when desired; these together with other novel features of construction of the parts of the machine,jwhich Will be more fully hereinafter described, 'constitute my invention.

Referring to the drawings: Figure 1. is a p1an=view of my improved drying machine showing the fan box in section; Fig. 2. is a vertical section on line 2-2Fig. 1; Fig. 3. is a vertical sectionon line 3-3 Fig. 1; Fig. 4. is a vertical section on line 4-4 Fig. 3; Fig.

i5. is a vertical section on line 5-5 Fig. 3;

and, Fig. 6. is a perspective view of the fan ox.` In the drawings 1 re resents a casing formmg the drying cham er 2, said casing 1 is preferably rectangular in formand is provided With.racks 3 'which divide the drying chamber into different-compartments 4 and 5 into which compartments may either be I placed the drawers 6, or poles 7, su ported upon racks or guides 8,`provided for t at purpose. The drawers have bottoms formed of wire mesh, upon which is laced the short ieces of dough. The dough is also dried in i on coils, such as shown at 10. These coils of ough are hung upon the. poles A7, which 1 are sus ended between the said cross-pieces 8,'whic in 'turn rest upon the racks 3. The

said cross-pieces 8 are removable, so that either the drawers 6 or the poles 7 may be used in any of the compartments as desired. The drying machine 1s provided with large doors 12 and 13, so as to make the interior of the drying chamber accessible.

The drying machine is provided with afan 15, `mounted in afan box 16. A shaft 17, supported in bearings 18 and 19,'carries the said fan or any otherY suitable means. v

The fan box 16 extends to the bottom of the drying machine, where the air-from the fan passes through the aperture 22 into the drying chamber, which is practically air tight, so that the air will be heid. under a sufficient pressure to uniformly dry the dough contained in the drawers or suspended upon the poles.

A stop-cock 23 is provided at the top of the drying machine, which may be opened to reduce the air pressure in the drying chamber when desired. A

The fan box is 'provided with a centrally located opening 24 having an adjustable cover 25, as shown in Fig. 6; which may be opened to admit fresh air to the fan. When it is desired to cause the air in the drying chamber to circulate, the aperture 26,

formed at the top of the drying chamber, as and 4, is opened by means of the rod 27, which is connected with a sliding door 28, adapted to tightly close said `aperture 26. When said aperture 26 is opened the air will be drawn from the top of the drying chamber into the return chamber 30, from which it is drawn, throu ing 31, into the fan box 16. Thco-ver 25, of the fan box may be closed so that the air in circulate, or the cover may be opened to admit fresh air as desired.

Having thus described my invention I claim and desire to secure by Letters'Patent:

In la drying room, the combination of a casing forming a drying chamber, a fan box h the open-l and is driven by the belt wheels 20,

located adjacent said drying chamber and having an aperture formed therein for admitting. air to the lower portion of said drying chamber, a fan in said fan box, said drying Achamber having an aperture formed inthe upper portion thereof, a return chamber eom- In testimony whereof I affix my :signaturev munieating with said aperture in the upper. in presence of two Witnesses.
